      Background InformationE3 ubiquitin-protein ligase AMFR (UniProt Q9UKV5; also known as AMF receptor, Autocrine motility factor receptor, gp78, RING finger protein 45) is encoded by the RNF45 (also known as AMFR) gene (Gene ID 267) in human. Glycoprotein 78 (gp78) is an endoplasmic reticulum (ER) membrane-anchored E3 ubiquitin ligase that plays a key role in ER-associated degradation (ERAD). Gp78 is localized to a mitochondria-associated ER domain, where it induces mitochondrial fragmentation by targeting the mitochondrial fusion proteins mitofusin 1 and 2 (Mfn1 and Mfn2, respectively) for degradation upon mitochondrial depolarization. Other known ERAD substrates processed by gp78 include ApoB lipoprotein, HMG CoA reductase, CD3-delta, cystic fibrosis transmembrane conductance regulator, the metastasis suppressor KAI1, unglycosylated prion protein (PrP), and the T-cell receptor. Gp78 is a 7-transmembrane protein (a.a. 82-102, 122-142, 145-165, 186-206, 215-235, 276-296, 429-449) with a RING-type Zinc finger (a.a. 341-379), a CUE domain (a.a. 456-498), and a VCP/p97-interacting motif (VIM; a.a. 622-640).

      Application NotesImmunocytochemistry: A representative lot detected glycoprotein 78 immunoreactivity colocalized with that of the mitochondria marker OxPhosV in COS-7 cells (Courtesy of I. Robert Nabi, Ph.D., University of British Columbia, Canada).

      Affects Function: A representative lot stimulated the mobility of B16-F1 mouse melanoma cells on colloidal gold-coated surface (Nabi, I.R., et al. (1990). Cancer Res. 50(2):409-414).

      Immunocytochemistry Analysis: A representative lot detected both surface and cytoplasmic gp78 immunoreactivity by fluorescent immunocytochemistry staining of intact or MeOH/3% paraformaldehyde-fixed and 0.5% Triton X-100-permeablized mouse A31 fibroblasts and A31M angiosarcoma cells (Niinaka, Y., et al. (1998). Cancer Res. 58(12):2667-2674).

      Immunocytochemistry Analysis: Clone 3F3A ascites fluid immunolocalized gp78 on the surface of adherent B16-F1 mouse melanoma cells by fluorescent immunocytochemistry staining of 3% paraformaldehyde-fixed cells (Nabi, I.R., et al. (1990). Cancer Res. 50(2):409-414).

      Immunohistochemistry Analysis: A representative lot detected an elevated gp78 immunoreactivity in frozen mammary gland sections from 235RLF transgenic mice than age-matched wild type mice (Joshi, B., et al. (2010). J. Biol. Chem. 285(12):8830-8839).

      Western Blotting Analysis: A representative lot detected shRNA-mediated gp78 downregulation in HT-1180 human fibrosarcoma cells (Fu, M., et al. (2013). Mol. Biol. Cell. 24(8):1153-1162).

      Western Blotting Analysis: A representative lot detected endogenous gp78 and gp78 transgene expression in mammary glands from wild-type and transgenic mice. Clone 3F3A detected a higher gp78 expression in metastatic MDA-435 cells than in non-metastatic MCF7 breast carcinoma cells (Joshi, B., et al. (2010). J. Biol. Chem. 285(12):8830-8839).

      Western Blotting Analysis: A representative lot detected much higher gp78 expression in angiosarcoma (human HT-1180 and mouse A31M) than in fibroblast (human IMR90 and mouse A31) lines (Niinaka, Y., et al. (1998). Cancer Res. 58(12):2667-2674).

      Western Blotting Analysis: A representative lot detected gp78 and a ~150 kDa band in B16-F1 mouse melanoma cell extract. Autocrine motility factor (AMF) competed against clone 3F3A for binding the gp78 target band. Cell extract sialidase treatment decreased the antibody's immunoreactivity toward gp78 and abolished ~150 kDa band detection (Nabi, I.R., et al. (1990). Cancer Res. 50(2):409-414).
